>From d6f1f292c3963c4f10fe0bf6de5fa79ff3e1ef30 Mon Sep 17 00:00:00 2001 From: John Dulaney <jdulaney@xxxxxxxxxxxxxxxxx> Date: Sat, 9 Apr 2016 03:44:35 -0400 Subject: [PATCH] Patch to fix compile issue with drivers/block/null_blk.c There is a line of invalid C in drivers/block/null_blk.c: static struct nvm_dev_ops null_lnvm_dev_ops; Its at line 568 in my checkout. This patch fixes this issue. Sourced from: http://comments.gmane.org/gmane.comp.emulators.kvm.devel/145455 I have done a test build that boots and runs normally.
